String.Empty vs ""

String.Empty vs ""

As Davidimplies, there
difference between String.Empty and “” are pretty small, but there is a
difference. “” actually creates an
object, it will likely be pulled out of the string intern pool, but still… while
String.Empty creates no object… so if you are really looking for ultimately in
memory efficiency, I suggest String.Empty.However, you should keep in mind the difference is so trival you will
like never see it in your code…

As for System.String.Empty or
string.Empty or String.Empty… my care level is low ;-)
